Skosmos 2.0

This is a major version of Skosmos. There are some user-visible changes, e.g., a copy to clipboard button, but lots of changes under the hood and many libraries have been updated to more recent versions. The new version requires PHP7 and uses a single configuration file instead of two separate files. There is now support for running Skosmos via Docker and also for setting up a development instance using Vagrant and Ansible.

Translation updates:

• #710 New Dutch translation by Ismail Kutlu and Maxime Van Driessche
• #767 New Arabic translation contributed by UNESCO
• New Farsi translation by Omid Ghiasvand and Reza Ghiasvand
• Updated German translation by Jonas Waeber
• Updated Polish translation by Łukasz Szeremeta
• Updated French translation by Thomas Francart
  Note that there is no support for right-to-left languages yet in the Skosmos UI, so the Arabic and Farsi localizations are not yet complete.

Skosmos 1.7

The most important improvement in this release is the new Swagger/OpenAPI description of the REST API.

Other new features include accessibility improvements, better support for reified definitions, and searching concepts by notation code. There are also performance improvements to the search result page, ability to configure SPARQL request timeouts and the possibility to disable the alphabetical index.
